(54)	ADAPTIVE WAVEFORM SELECTION IN WIRELESS COMMUNICATIONS

(57) Systems and methods of wireless communication in which wireless devices are adapted to implement adaptive waveform selection are disclosed. For example, a wireless device may determine a waveform to use for at least one uplink transmission associated with a random access channel (RACH) procedure, wherein the determining of the waveform is based on a system information block (SIB), a first message of the RACH procedure, a second message of the RACH procedure, a measurement, or a combination thereof, and wherein the waveform is determined from a plurality of waveforms including a single-carrier frequency division multiplexing (SC-FDM) waveform and an orthogonal frequency division multiplexing (OFDM) waveform. Also, the wireless device may transmit a message corresponding to the RACH procedure based on the determined waveform.
